Is it true that... cycling affects fertility?
Saddling up is only likely to be an issue for elite athletes – and those with low sperm counts
TL;DR
- Cycling is not a primary concern for most fertility doctors.
- Extreme levels of cycling can affect fertility, particularly for elite athletes.
- For women, high physical activity can lower body fat, potentially switching off ovaries and reducing fertility.
- For men, prolonged time on a bike saddle can increase temperature around the testicles, affecting sperm production.
- Moderate cycling has no discernible effect on sperm count.
- Extreme cycling may slightly change sperm count, but this is more relevant for men with already borderline counts.
- Fertility experts consider lifestyle factors like smoking, drinking, and saunas, and may advise moderation.
